IMPROVED GRTAIN-FIXTURE..

@In tlgentle mimi it in tlgeetter gnent sin making part nf tigt same.

Be it known A,that I, ALFRED YOUNG, oil the `eity'and county 'oi' Philadelphia., State of Pennsylvania, have invented a new and useful rIlltpn'overlient in Window-Shades, which are raised and lowered by means of cylin drical rollers. I hereby declare that the following s a full, clear, and exact description. of the same, reference ,being had'to the annexed drawings, which I hereby make part of this specication, in whichl l i Figure 1' is'a front elevation.' v I i `Figure 2 isa section through :v y oi' g. 1;

.In the drawings, like gures referto like parts. 4

a a a a'represent the ordinary windomframe.; t Z1 Vb b, the curtain ,to be raised and lowered; ce, the roller; d ci', brackets supportngrthe'rolleri e e, the pulley; ff, the cord; g g, springs fastened to frame of window and bearing upon curtain.

I now proceed to describe the operation oi' this improvement. I place the springs g g, one at each end onfv roller', or more, if necessary, .in such manner that they bear upon the curtain prevent any looseness in winding, and keep-it evenlyA strained, so that it is caused to roll up smooth, even, and straight,.a nd prevented from riding over the guards at ends, whether the curtain' be hanging perpendicular or not. This result will generally be obtained by the'simple spring g g, Yas seen in fig. 2. This curved spring tting'around and over the roller, prevents the curtain, where it comes upon thero'ller, from being raised oif the roller, and thus assists in the result.

What I claim as my invention, and desire to secure by Letters Patent,l is-.

The springs g'g, fastened to the frame of'the window, and bearing upon the curtain in such manner that the curtain will be tightly and evenly straned. i I

y ALFRED YOUNG. Witnesses:
